[Bug 1583288] Re: Realtek Wifi card rtl8723be [10ec:b723] WiFi not available
apport information
** Tags added: apport-collected rosa
** Description changed:
I am here on a HP Pavilion Laptop with beatsaudio. No Model Number -
nothing.But I have this problem on other HP (455) Notebooks too.
OS tried: OpenSuse / Kubuntu / Linux Mint Mate (card does not work out
of the box / no scanning)
The Wifi card is: (in Germany!)
--------------------------------------
lspci -nn | grep -iA2 net
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]
--------------------------------------
I am now under kernel:
4.4.0-21-generic
I installed the newest kernel because in some threads people said the card woule be available in the newest kernel. But this was not the case. I mean the card is there but does not scan nor see any wifi networks.
-------------------------------------
Before I tried everything I could find to get my wifi running but I do
not even see one spot. So no connection at all. I even cloned git and
compiled the driver - the compiling and installation worked fine. I
tried the old and the new driver.
By the way the BT seems to be fine - although I have not checked cause I
do not need BT.

"There is a new version of this driver at GitHub. You will need to have
the package with the kernel headers installed.
git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
This version of the driver will be submitted for inclusion in kernel
3.18. I ran it for 39 hours with no disconnects."
---------------------------------
no errors but no change.
---------------------------------
Checked this link:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1240940
---------------------------------
Then I tried several params and finally this worked somehow.
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be msi=1
I now was able to see wifi networks - hoorayyyy!! :)
---------------------------------------------------------
I then tried to connect to my network - but failed.
I am sitting 1 m next to my router.

WORKAROUND: I changed region to Germany:
echo 'KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/iw reg set DE"' | sudo tee /etc/udev/rules.d/regulatory.rules
and then I was able to connect. My options are now:
options rtl8723be fwlps=0 swlps=0 msi=1
Now it runs perfectly! Thanks to all!!
